Hadron component of EAS cores detected at Tien-Shan mountain station in comparison with CORSIKA+QGSJET simulations

In this paper we study how the knee in primary cosmic ray (PCR) spectrum can reveal itself in the hadron component of EAS cores. The comparison of CORSIKA+QGSJET calculations with available experimental data at mountain level (3340 m a. s. l.) shows that the suggestion about rigidity dependent energy position of the knee and the moderate change of spectrum slope in every nuclear component of PCR does not contradict experimental data.
